球齿钻头布齿的优化方法探讨

Optimization of the InsertArrangement for Button Bits

摘要:

在等工作条件布齿理论的基础上，从球齿碎岩机理出发，探讨了相邻球齿对碎岩效果的影响，从而确定了最优齿间距，并确定最佳齿位和合理的齿数。

Abstract:

Based on the rule of the insert arrangement in equal running condition, the effect of the button inserts in the vicinity on rock fragmentation is explored, and the optimum insert spacing, best insert position and proper insert numbers are determined.
